2 Connecting to CC-Link
Wiring to the CC-Link controller (LK-CC100)
The LK-CC100 field network connector (terminal block) is to be wired as explained below.
• To connect the CC-Link controller to the CC-Link, use the CC-Link dedicated cable (Ver. 1.10 or
higher).
• At each CC-Link station connection, connect the cable shield to FG.
Typical connection
Refer to the manual for the CC-Link master unit for wiring details.
Connecting terminators
A terminator must be connected to both ends of the
trunk line. The terminators must be connected to
reduce signal reflection and stabilize communication.
Terminator resistance: 110 ohms, 1/2W
• The terminators must be connected, otherwise, the CC-Link
will not communicate properly.
• If using the CC-Link dedicated high-performance cable,
use a 130 ohm, 1/2W resistor.
Terminal name Function
FG Functional ground terminal.
Ground to a ground resistance of 100 ohms or less.
SLD Shield.
Connect shield wire from the dedicated CC-Link cable
supporting Ver. 1.10 (OP-79426, OP-79427, etc.).
